About General Butler from Wikipedia:
Smedley Darlington Butler (July 30, 1881 – June 21, 1940), nicknamed “The Fighting Quaker” and “Old Gimlet Eye”, was a Major General in the U.S. Marine Corps, and at the time of his death the most decorated Marine in U.S. history. During his 34-year career as a Marine, he participated in military actions in the Philippines, China, in Central America during the Banana Wars, the Caribbean and during World War I, he served in France. By the end of his career he had received 16 medals, five of which were for heroism. He is one of 19 people to be twice awarded the Medal of Honor, one of three to be awarded both the Marine Corps Brevet Medal and the Medal of Honor, and the only person to be awarded the Brevet Medal and two Medals of Honor, all for separate actions.
In addition to his military achievements, he served as the Director of Public Safety in Philadelphia for two years and was an outspoken critic of U.S. military adventurism. In his 1935 book War is a Racket, he described the workings of the military-industrial complex and, after retiring from service, became a popular speaker at meetings organized by veterans, pacifists and church groups in the 1930s.
Excerpts from his book “War is a Racket”
“War is a racket. It always has been. It is possibly the oldest, easily the most profitable, surely the most vicious. It is the only one international in scope. It is the only one in which the profits are reckoned in dollars and the losses in lives. A racket is best described, I believe, as something that is not what it seems to the majority of the people. Only a small ‘inside’ group knows what it is about. It is conducted for the benefit of the very few, at the expense of the very many. Out of war a few people make huge fortunes.”
“I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. In short, I was a racketeer, a gangster for capitalism. I helped make Mexico and especially Tampico safe for American oil interests in 1914. I helped make Haiti and Cuba a decent place for the National City Bank boys to collect revenues in. I helped in the raping of half a dozen Central American republics for the benefit of Wall Street. I helped purify Nicaragua for the International Banking House of Brown Brothers in 1902-1912. I brought light to the Dominican Republic for the American sugar interests in 1916. I helped make Honduras right for the American fruit companies in 1903. In China in 1927 I helped see to it that Standard Oil went on its way unmolested. Looking back on it, I might have given Al Capone a few hints. The best he could do was to operate his racket in three districts. I operated on three continents.”
